“…Additional analyses on historical spot market prices in the period from 2001-2006 demonstrate that the annual net earnings vary significantly between the years. Still such analyses show that the practical net earnings are likely to be in the range of 80 to 90 per cent compared to the optimal earnings [30].…”

“…Various studies by researchers from universities, consultancy companies, the Danish TSO Energinet.dk and the Danish Energy Agency have examined how to deal with such a challenge [7,28,[56][57][58][59][60][61][62][63][64][65][66][67][68][69]. From these studies, the following results can be highlighted:…”

Denmark has more than 10 years of experience with a wind share of approximately 20 per cent. During these 10 years, electricity markets have been subject to developments with a key focus on integrating wind power as well as trading electricity with neighbouring countries. This article introduces a methodology to analyse and understand the current market integration of wind power and concludes that the majority of Danish wind power in the period 2004-2008 was used to meet the domestic demand. Based on a physical analysis, at least 63 per cent of Danish wind power was used domestically in 2008. To analyse the remaining 37 per cent, we must apply a market model to identify cause-effect relationships. The Danish case does not illustrate any upper limit for wind power integration, as also illustrated by Danish political targets to integrate 50 per cent by 2020. In recent years, Danish wind power has been financed solely by the electricity consumers, while maintaining production prices below the EU average. The net influence from wind power has been as low as 1-3 per cent of the consumer price.

“…Moreover, most batteries contain toxic materials, which may cause environmental harm if they are not recycled properly. CAES is a developing technology that has the potential to meet the needs of intermittent sustainable energy sources and high peak load electrical power demands, with a very long service period, low cost of energy, low cost of maintenance and operation, and high power efficiency by storing energy during off peak periods [23]. Recently, CAES has emerged in building a range of small-scale energy storage products.…”

Small wind turbines are commonly single-turbine installations owned by individual homeowners or farmers for on-site electricity consumption, and are becoming an attractive alternative for off-grid electrification and water pumping, both as stand-alone applications and in combination with other energy technologies such as photovoltaic, small hydro or diesel engines. The cost of energy alone is not the only criterion to consider, other aspects like system performance, suitability for a given wind regime, reliability under normal and extreme wind conditions, efficiency in energy storage and exploitation, and overall system life are often equally important. This research deals with the development of small-scale wind energy systems for increasing the productivity of wind power and achieving the better exploitation of generated energy. The proposed wind turbine controller is based on the variable-speed variable-pitch power regulation strategy, using the combination of chattering torque control and PI pitch control. The hardware-in-the-loop (HIL) simulation and on-site experimental testing in rural area are presented. Compressed air energy storage (CAES) strategy for the energy exploitation is also discussed.
